    Metadata Updated: September 27, 2025

    This project is conducting seasonal deployments to investigate carbonate chemistry and monitor ocean acidification in the Gulf of Maine. The glider used for the automated observation includes an integrated deep rated version of the Ion Sensitive Field Effect Transistor (ISFET)-based pH sensor. The pH sensor unit is complemented with existing glider sensors including a CTD, a WETLabs FLBBCD ECO puck configured for simultaneous chlorophyll fluorescence and optical backscatter measurements, and an Aanderaa Optode for measuring dissolved oxygen. The real-time dataset contains CTD, chlorophyll a, CDOM and optical backscatter measurements. Dissolved oxygen and pH data will be processed post-deployment.
